Step-by-step explanation:
The Mini-ITX motherboard form factor has the smallest footprint for use in thin client devices. It measures just 6.7 inches x 6.7 inches (17cm x 17cm), making it significantly smaller than other form factors such as ATX or micro-ATX. This compact size makes it ideal for use in small form factor devices such as thin clients, as well as embedded systems and other compact applications where space is at a premium. Despite its small size, Mini-ITX motherboards are still able to offer a full range of features and capabilities, including support for processors, memory, and expansion cards.
